Manual Tuneable Filters

Based on a proprietary thin film cavity filter technology, Agiltron offers PM Fiber Optic Tuneable Filter with central wavelengths ranging from 450 nm to 2000 nm. It is tuneable continuously over a wide spectral range up to 80nm. Agiltron further offers high optical power handling up to 10 W(CW) while maintaining the transmission spectral shape polarisation-insensitive over the whole tuning range. Agiltron’s unique high reliability and low insertion loss design presents a most cost-effective solution for OEM applications from fibre optic networks to fibre sensing interrogation.

Wideband Tunable Filters of WLTF-WM- & WLTF-WE- series are built based on free-space optical Fourier transformation combing with diffraction grating. Unique optics design produces an access of selecting spatially desired spectral ingredients of input light and offers flat-top transmission spectral shape with flexible bandwidth and unprecedented low insertion loss and polarization dependent loss (PDL). Precise tuning mechanism enables filters to provide high wavelength resolution and excellent wavelength repeatability.
